title: Methyl 9-hy-droxy-15-methyl-2-oxo-11-(pyren-1-yl)-10-oxa-15-aza-tetra-cyclo-[7.6.0.0(1,12).0(3,8)]penta-deca-3(8),4,6-triene-12-carboxyl-ate.
abstract: In the title compound, C32H25NO5, the furan and pyrrole rings each adopt an envelope conformation, the respective flap atoms being the C atom bearing the pyrene substituent and the CH2 atom adjacent to the N atom. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. In the crystal, C-H⋯O contacts link the mol-ecules, forming a two-dimensional network parallel to (001).
